Assange told the British newspaper that he will receive $800,000 from Knopf while his deal with Canongate is worth £325,000, or approximately $502,000.

WikiLeaks came under financial trouble when Paypal, MasterCard and Visa recently cut off all processing of donations to the site. According to Assange, the site has lost approximately $650,000 since this funding was cut off. At its peak, the site was receiving approximately $130,000 in daily donations, he says.

The site, which has been up and running since 2006, has repeatedly created controversy since April, when it released a video of a 2007 Baghdad airstrikethat shows a U.S. army air-to-ground attack that killed two members of the Reuters news staff.

In late November of this year, WikiLeaks and five worldwide newspapers began to leak over 250,000 American military and diplomatic cables from 274 U.S. embassies around the world.

Assange is not the first person from WikiLeaks to ink a book deal. Crown Publishers announced on Wednesday that the site's former spokesman Daniel Domscheit-Berg, also known as Daniel Schmitt, will be releasing a book in February.

Domscheit-Berg has said that the book, "Inside WikiLeaks: My Time with Julian Assange at the World's Most Dangerous Website," "will reveal the evolution, finances and inner tensions" at the controversial website.

Domscheit-Berg left WikiLeaks three months ago, and has said he plans to launch a new platform for leaking classified information, called Openleaks.org, early next year.
